Performance

1. HFV-A series oil has wider temperature range compared to the M series.  

2. Better anti-wear ability to reduce interface wear when compressing.

3. Superior oxidation stability to effectively extend the oil-change intervals.

4.Desirable foam characteristics to reduce wear due to overflow and interruption of work

 fluid.

5.  HFV-A series oil keeps pump running at high vacuum degree,with a much longer

 service life.

 

Application         

1. Applicable to poor working conditions and keeping good vacuum degree under conditions of high, pressure or high load.

2. Can be applied to various domestic and foreign vacuum pumps such as the British Edwards,German Leybold,French Alcatel and Japanese Ulvoil.
